Recycling wastage to energy

Coming
to waste management, it is always a hassle for the authorities to find a
complete solution in disposal of the same. Developing countries like India,
where wastages are dumped directly into public places and water resources; it
is an intricate situation which is not addressed yet. Polluted air and water
are the major cause of environmental crisis in India. Lack of sophisticated
system to dispose wastages lets the public and government authorities ignore
the importance of neat and clean environment. Social responsibility is always
treated as a ‘not my job’ thing by them.

Convert waste to energy

However,
this article looks more into the recycling of wastage and generating energy
through it. Recycling wastage to energy is a part of waste management. In many
developed countries, wastages are used as raw material for producing energy,
gas etc. This recycling not only benefits the environment but also reduces the
production cost and resources. It is economical and reduces pollution due to
wastages dumped into open areas and water resources.

There
are many methods used for converting wastages to energy. The most conventional
method is direct combustion where the heat generated by wastages is converted
to energy using steam turbine. In countries where homes needed to be heated,
the heart from wastages is circulated using warm hole. Thus they can avoid the
use of electrical equipments to get heat. Fuel also can be generated from
waste. Methane generated from landfill gas is a fuel produced from wastage. Anaerobic
digestion is another method to produce bio-gas from wastages like sewage, food
waste etc. The bio-gas thus produced can be used directly for cooking and
heating home.

Along
with conventional methods of producing energy from wastage, advanced technologies
are also being used by many countries. Gasification is an advanced conversion
to produce combustible gas which is a combination of carbon monoxide, hydrogen,
carbon dioxide and methane. This gas is ready to use directly for generating
heat and electricity. Pyrolysis is another method of conversion to produce
combustible gas, oil or solid char (sometimes known as biocoal). Technology can
be chosen depending on the nature of available wastage.

The
recycling of wastage contributes a lot to the environment, society and health
related solutions. Instead of depending of natural resources to produce energy,
which often distracts the eco-system, a well planned system to produce energy
is more economic and eco-friendly. It not only gives clean and safe environment
and water to humane, but it also protects other species that equally shares
this world with us. Inhabitants of oceans for example, discharging bulk amount
of wastage into ocean have put inverse effect on the inhabitants. Wastages
turned poison kills millions of creatures under water and sometimes it leads to
the extinction of a species from the earth.

Who
would like to live in a stinky atmosphere? Whether it is human or animal, we
all need fresh air and water to lead a healthy life. Sophisticated methods to
dispose wastage will definitely help in creating a world that smells sweat.
